你能告诉我问题出在哪里吗?我有一个文件GeneratorTest.php与以下测试:
<?php
namespace statsTest;
use statsjwayFile;
use statsjwayGenerator;
class GeneratorTest extends PHPUnit_Framework_TestCase
{
public function tearDown() {
Mockery::close();
}
public function testGeneratorFire()
{
$fileMock = Mockery::mock('statsjwayFile');
$fileMock->shouldReceive('put')->with('foo.txt','foo bar')->once();
$generator = new Generator($fileMock);
$generator->fire();
}
public function testGeneratorDoesNotOverwriteFile()
{
$fileMock = Mockery::mock('statsjwayFile');
$fileMock->shouldReceive('exists')
->once()
->andReturn(true);
$fileMock->shouldReceive('put')->never();
$generator = new Generator($fileMock);
$generator->fire();
}
}
这里是文件和生成器类: File.php: class File
{
public function put($path,$content)
{
return file_put_contents($path,$content);
}
public function exists($file_path)
{
if (file_exists($file_path)) {
return true;
}
return false;
}
}
Generator.php: class Generator
{
protected $file;
public function __construct(File $file)
{
$this->file = $file;
}
protected function getContent()
{
// simplified for demo
return 'foo bar';
}
public function fire()
{
$content = $this->getContent();
$file_path = 'foo.txt';
if (! $this->file->exists($file_path)) {
$this->file->put($file_path,$content);
}
}
}
因此,当我运行这些测试时,我收到以下消息:BadMethodCallException:Method … :: exists()在此模拟对象上不存在.
解决方法
错误消息对我来说似乎很清楚.您只设置了put方法的期望,但不存在.所有代码路径中的被测试类都调用exists方法.
public function testGeneratorFire()
{
$fileMock = Mockery::mock('statsjwayFile');
$fileMock->shouldReceive('put')->with('foo.txt','foo bar')->once();
//Add the line below
$fileMock->shouldReceive('exists')->once()->andReturn(false);
$generator = new Generator($fileMock);
$generator->fire();
}
